At every turn, your feedback shaped Readmill’s development, and your passion signaled a new chapter for reading. Together we wrote in the margins of ebooks and discussed our favorite passages from across the world. Thank you for helping to bring this reality into view.

Readmill’s story ends here. Many challenges in the world of ebooks remain unsolved, and we failed to create a sustainable platform for reading. For this, we’re deeply sorry. We considered every option before making the difficult decision to end the product that brought us together.

It's going to be pretty hard to create a reading app or ebook store that does more than sit on the margins. The last figures that I saw had Amazon at 60-70 %, B&N 15-25 %, Apple 10-20 % and everyone else at < 5%.

You could use Readmill to extend the Kindle Highlights page and import it into their site. A few apps used their API to create mobile/web apps in which you could then use to study these among other stuff. It had great potential, just not a lot of developers wanted to tap into it.

You could also read books with their apps and do highlights within them.

I'm one of Readmill's saddened users. The app was pleasantly effective in its purpose. It embraced a philosophy of simplicity —there were no typeface choices, only size—, but the available options were well selected. The visual rendering of text was really beautiful, and I hope other reading apps to give (even) more attention to this aspect. The cloud storage was very easy, and all the social aspect of reading and the treatment of highlights and annotations were a strong point of distinction. Anyway, I may say that my sadness isn't bigger because there are plenty of alternatives, on iOS and Android, some of which I already use (Kindle, Marvin, Moon+ Reader, etc).
